94. Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit card logo. Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.
Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
(A) The effect noted in the studies is not limited to patrons who have credit cards.
(B) Patrons who are under financial pressure from their credit-card obligations tend to tip less when presented with a restaurant bill on a tray with a credit-card logo than when the tray has no logo.
(C) In virtually all of the cases in the studies, the patrons who paid bills in cash did not possess credit cards.
(D) In general, restaurant patrons who pay their bills in cash leave larger tips than do those who pay by credit card.
(E) The percentage of restaurant bills paid with a given brand of credit card increases when that credit card’s logo is displayed on the tray with which the bill is presented.
用现金付账的客户通常消费留的更多，当看到托盘上的信用卡标志时。结论是，看到信用卡标志可以使信用卡持有者花费更多，这提醒他们购买力超出了他们有的现金。
a）并不局限于有信用卡的客户。
b）信用卡上欠钱的人小费给的少如果她们看到托盘上有信用卡标志
c）事实上研究中的，用现金买单的人都没信用卡
d）通常，用现金买单的人留小费比用信用卡买单的人多
e）忽略不计。。。。。
为什么答案是B啊？
至少觉得B选项并没有起到support的作用啊，搞不清楚用现金付钱和信用卡标志的关系。还有D选项为什么被判为weaken？作者: nancy5130 时间: 2013-1-10 20:35
